LMV1015 Analog Series Built-in Gain IC’s for High Sensitivity 2-Wire Microphones May 2005 LMV1015 Analog Series: Built-in Gain IC’s for High Sensitivity 2-Wire Microphones General Description The LMV1015 is an audio amplifier series for small form factor electret microphones. This 2-wire portfolio is designed to replace the JFET amplifier. The LMV1015 series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, such as in cellular comwww.DataSheet4U.com munications. The LMV1015 audio amplifiers are guaranteed to operate over a 2.2V to 5.0V supply voltage range with fixed gains of 15.6 dB and 23.8 dB. The devices offer excellent THD, gain accuracy and temperature stability as compared to a JFET microphone.
